Abstract
Filter arrangements for mist removal include a barrier media, usually pleated, and treated with a deposit of fine fibers. Filter arrangements may take the form of tubular, radially sealing elements; tubular, axial sealing elements; forward flow air cleaners; reverse flow air cleaners; and panel filters and can have multiple layers of fine fiber containing pleated media.
